There can be a level of uncertainty when it comes to buying anything online. That fact that we aren't tangibly holding the item in our hands, is an act of trust. We are trusting a company, who's people we have never met, to deliver an item we haven't seen yet, after we give them our money! It sounds a bit surreal. Internet shopping, however, has come a long way. There are services and agencies that take on some responsibility for these companies. The option to dispute charges has also made us more comfortable with the idea.
